Another of my Durham observations was church windows - from the outside. At the time my interest mainly related to the shapes and patterns that could be seen.
St Nic's in the Market Place
The wonderfully named "Our Lady of Mercy and St Godric's"
This one is from the Cathedral - and when Dolly D saw it she remarked, "It looks different from the outside". It strikes me that this statement could equally apply to churches ancient and modern.
The window that I like most was the one below - from Elvet Methodist with the late afternoon sun catching the simply pattern.
The analogy that springs to mind - let your light shine before men. How much light do our churches actually emit?
